> For the Ryzen 3000-series processors, CCX refers to a four-core grouping inside of each core chiplet die (CCD). For example, an AMD CPU with 8 cores will have a CCD with two 4-core CCXs.
From that link, your statement does not appear accurate. Multiple CCX's appear on a given Core Chiplet Die. There are indeed two vs one core chiplets on different Ryzen designs (plus the IOD).
This is a minor terminology mix-up. The term you want here is "CCX". Each CCX holds multiple chiplets.
See https://www.tomshardware.com/reviews/amd-ccx-definition-cpu-... for more details.
EDIT: It does look like my own information on this was rusty.
A "chiplet" is not an individual core, but a trimmed down die that does not have a memory controller. A "CCX" contains cores (within a chiplet) and L3 cache.
